New device allows disabled people to draw on a computer using only their eyes

A French researcher has built a device allowing disabled people to write or
draw on a computer screen using only their eyes, a report said Thursday. 

With head-mounted cameras monitoring their eye movements, test subjects were
able to write and draw on a blank computer screen in the latest breakthrough
for people trapped in immobility by disease or accident.

Device Helps Eyes Do the Write Thing
From: Wall Street Journal - 07/26/2012
By: Robert Lee Hotz 

French National Center for Scientific Research director Jean Lorenceau has
developed a device that enables users to write with their eyes in cursive
script on a computer monitor. "It's like drawing with a pencil, but without a
tip," Lorenceau says. Users wear a small infrared video camera to relay their
eye movements to the computer screen. It has been problematic for researchers
to develop computer-controlled systems in which users voluntarily produce
smooth, controlled eye movements. In order to overcome this problem,
Lorenceau used an optical illusion called "reverse phi-motion," which uses
patterns of contrasting dots on a video screen to create a flickering
illusion of motion. He says the illusion helps users gain the precise eye
control necessary for cursive script by providing a way for motion-sensitive
neurons to orient themselves. During testing, users were able to produce
legible script on a computer screen at a rate of 20 to 30 characters per
minute.
